Abstract

Die Erfindung betrifft einen Adapter für einen Extruder zur Erzeugung von Kunststoffprofilen, der dazu vorgesehen ist, zwischen einem Extruderzylinder (2) und einer Extrusionsdüse (20) angeordnet zu sein, wobei ein Grundkörper des Adapters einen Fließkanal (6) aufweist, der an einer Außenseite durch eine Wandfläche des Grundkörpers und an einer Innenseite durch einen fest mit dem Grundkörper verbundenen Umlenkkörper (3) begrenzt ist. Eine schonende Homogenisierung der Schmelze kann dadurch erreicht werden, dass der Umlenkkörper (3) im Wesentlichen kugelförmig ausgebildet ist und ausschließlich von einem stromaufwärtig gelegenen Haltedorn (4) gehalten wird, der über Stege (17) mit dem Adapter (1) verbunden ist.

Figure 00000001
The invention relates to an adapter for an extruder for producing plastic profiles, which is intended to be arranged between an extruder cylinder (2) and an extrusion nozzle (20), a base body of the adapter having a flow channel (6) on an outside is delimited by a wall surface of the base body and on the inside by a deflection body (3) which is firmly connected to the base body. A gentle homogenization of the melt can be achieved in that the deflecting body (3) is essentially spherical and is held exclusively by an upstream holding mandrel (4) which is connected to the adapter (1) via webs (17).
